I also installed a manifold from 1AAuto and that thing went on super easy. I didn't even have to use PB. I was able to see the crack in the old manifold and it was pretty bad. There was a crack about half way around one of the tubes. The engine is much more quiet.
That was just testing the heating element of the O2 sensor, should be between 5-7; infinity reading is bad. So unless you pull the voltage test, or getting a code from the computer then I say run it IMHO.
I had the same crack in my manifold, I was able to get away with just welding it, but it doesn't always work (sometimes you chase the crack). Glad to hear it is working well. Have to get some miles on there and see how the mileage goes.
